nail, in the county of milton, in the State oi iill1io,lravc in'vcnted e 1 ew and useful Music-Recording Device, which the following is :i specific tion.

Qur invention, of which the following is va specification, relates to the utilizing of the touch of the performer when exerted in ploy ing on time keys of the instrument to thereby set in motion (by mechanical or, preferably, electrical transmission) a number of le' provided rs'ith fountain-pens or, preferably, small revolving disks or points of alisor 've materiel carrying ink in such a way that at each stroke oi a key e dot or dash (of length proportionate to the time the key 'is depressed.) will he recorded on slip of paper kept in motion at e uniform speed by rolls actuated by e motor which is controlled by a governor.

The object of our invention is twofold. It either to moire a record of such dimensions that by punching out each dot and dash it will once be transformed into a serviceable and true music-roll for any self-player, such as the pisnole or ceeilisn, doc, or to nmlre a record on a special music-staff of our own design, which, owing to its similarity to the ordinary music-start with notations, will he at once comprehensible and readable to thennilsicisn and for that person can he readily copied or written out into regular two-stsli music. By this means it will he posriwle JO preserve improvisations on the piano or org on and to make instantaneous notations for permanent record of nascent compositions, so as to render to the compose the same service that stenogropliy to the author and speaker. We attain these objects th e mechanism illustrated in the scccmpon vings, in wl1ich V Figure 1 shows a series of electrical contests seed at it convenient point under the \7- Fig. 2 shows a longitudinal top rise of electrical contacts. Fig. the complete recording device a o otng the pspenrolls to be stem"; i i so on the selllayers, (the piccolo, Y shows toe recording device adapted to the still more narrow roll, having our peciel sterl printed on it. The white lreys are recorded. in their proper place on tho start? by black msrlrs and the black keys by roar fencer monies, residing in Cincinmsrlrs ol s dill'erent color. Fig. 5 is e perpendicular section of 1111 complete stair as printed on the paper-roll used in the lacy-recording device liig. is :1- disgrsm oi' a soction of our stall, considerably enlarged, as

to show d'stinctly the method of recording by different colors the white and the block k6 in their respective places. 7 is it diagrzinnnatic view showing the circuit arrongeinents between the battery, electromagnets, and the cont-acts oi the keyboard.

in Fig. the wires C D show the :JOllIl-GC- tion between the battery, one contact, and one elcctronmvgnet L L, which controls tl e lever E, which carries the marking device i, which in turn marks the paper G at a given point over the 'cod 1 as the paper being wound irom spool K to spool J by the springmotor H. When t is performer strikes e given key, the spring B is depressed, which instantly closes the electric circuit at A be tween control strip A" and contact-ringers B and keeps it closed as long as the performers finger lrccps key do sed The current then flows through the wires C D to the pertic-ulsr clectromegnct L L which corresponds to the particular key depressed. This in draws down the lever E and holds it long its relative key is held down. The heir held down by the electromagorings the marking, device l into contact. with the moving or G at gin en point over the center oil. bed i, and consequently a marl; is begun on. tile moving paper. This mark is continued: as long the performer keeps the circuit closed lay lioldinguthe-lrey down. The paper roll moving from spool govcrrmr/whiclr controls t e motor H, will re s-t i r. dots and desire. m srions lengths running in parallel at equal levers in a state 'of rest are from the elcctromngncts b 11g or ises the mar oliz ii state oi to he held oginnst c supply-roller om nlr, which is pieced a cove then'i and otinrotstionl1 y the spr' mo tor ct es org, but in i J eld sway carried out, not in this drew lhe motor st .ii is the ordinary springmotor used for nmsiccores and phonogrophs,

one, with a governor to control speed; out

s, which any motive power may be substituted, so long as it is capable of producing a uniform-rate of speed.

In Fig. 4, G shows the paper on which is printed our special recording-staff. This paper in motion slides over bed I, where the printing takes place. That portion of the levers E corresponding with the white keys of the piano are on one side of the supportingframe, While on the other side are those corresponding .vith'the black keys of the piano. When these levers are at rest, the little re volving disks F are pressed, by means of springs Q, against the ink-supply rollers P, which are kept revolving by pulleys (not shown in the diagram) driven by the springmotor. The electromagnets L L are arranged in tiers of nine, (9,) and the magnetic 'arrnatures at O are connected with the levers E by connecting-rods N, so that when the circuit C D is closed the annature O rises and by the rod N pulls up the short end of the lever E, which throws the long end of the lever carrying the marking-roller F away from the ink-supply roller P and causes it to register upon the special staif-paper G in its proper place. The levers E are arrangedin two sets, one on either side. One side rests against the revolving ink-supply roller P, carrying black ink, and registers in black marks on the paper all the white keys on the piano. ()n the other side the levers rest against the revolving ink-supply roller P, which carries red ink, and when they register on the stailthey print and register the black keys on the piano in red lines.

F ig. 5 represents a perpendicular section of our special staff composed of the two ordinary stafi's of five (5) black lines each, one for the treble and one for the bass clel's, with one dotted line'or line of a difl'erent color at equal distances between them, and with three (3) dotted or of a diil'erent color lines added below them and five (5) dotted or colored lines added. above them, as illustrated, to which additional dotted or colored lines may be added, if desired, either above or below. This staff is to be printed on the paperroll before using it with the device illustrated In Fig. 4.

Fig. 6 illustrates an enlar ed portion of said special staff with the blac and red lines in the relation in which they are printed on the special staff by the device Fig. 4.

We are aware that prior to our invention the spring-motor with governor, the moving paper-roll, the marking devices, and the electromagnet have all been used. We therefore do not claim them as original; but

What we do claim as our invention, and desire to secure by Letters Patent, is.

1. In combination with means for feeding a paper strip, a series of electromagnets arranged in superimposed relation above said strip, a support underlying said electromagnets, spring-pressed levers carrying marking means at their lower'ends pivoted on oppo site sides of said support and having their marking means extending beneathsaid support, armatures for said electromagnets, connections between said armatures and said levers, and inking-rollers in said support normally engaged by said marking means.

2. In combination with means for feeding a paper strip, a support overlying said means, two series of levers pivotally secured to said support on opposite sides thereof, each of said levers carrying marking means on its lower end, a bed disposed beneath said marking means and having said paper strip passing thereover, and means for operating said levers' 3. in combination with means for feeding a paper strip, a support, series of levers pivotally suspended from said support on opposite sides thereoi', marking means carried by the levers, a bed underlying said support and having said paper strip passing thereover, a series of electromagnets, armatures for said magnets, and veriically-extending rods connecting the outcw-ends of said levers and the outer ends of the arimrtures.

in testimony whereof we have signed our munesto this specification in the presence or two subscribing witnesses.
